Wikimedia Foundation projects

The Wikimedia Foundation (WMF) is a non-profit that owns the trademarks to and provides hosting and technical support for many open-knowledge projects, mostly famously Wikipedia. The intersection of OSM and WMF projects is multi-faceted.

WMF projects include:

• Wikipedia: encyclopedia
• Wikidata: structured data repository
• Wikivoyage: travel guide
• Wikimedia Commons: free media, mostly images. OSM tiles can be ported to here for maps. There is an extensive WikiAtlas project there.
• Wiktionary: dictionary
• Wikiquote: quotation repository
• Wikisource: original source documents
• Wikibooks: textbooks
• Wikiversity: general learning resources. An existing resource related to OSM is Humanitarian Open Streetmap.
• Wikispecies: taxa hierarchy

Additionally, some behind-the-scenes projects include:

• Meta-Wiki: discussion about the projects themselves and larger-scale planning. See discussion of OSM there.
• MediaWiki.org: hosting for the the software and extensions to it. See Maps there.
• Outreach: a site for interacting with the public. A possible hub for posting best practices, success stories, etc.
• Wikimania: conferences intended to discuss wikis
